Recent B7100 purchase.

I set the brakes and then forgot they were set, and discovered that in gear I could move the tractor. I have no problems coming to a stop during normal operation.

So, when brakes are set, is it normal to be able to overcome the brakes?

Yes, depending on what gear you are in. The tractor has drum brakes, which aren't real strong (discs hold better). But, because tractors move so slow, drum brakes work fine. That being said, in low gear, you can overcome the stopping power of the brakes, especially if the shoes are worn down.
My dad had an F250 Powerstroke. In 1st gear high range, you could hold the brake pedal down as hard as you want, let out the clutch, and the truck would still move.
The question them becomes this- are the brakes strong enough to stop the tractor when you want, and with a load? That is more relevant.

If I set mine on the first notch of the lock I can barely get it to crawl, but if I set it to the second notch it will stall the tractor.
I guess I've just got a really good set of brake shoes!;)
And no I'm not lacking HP, I upgraded my B7100 to 21.5 HP.:D

It is one of the most annoying things about most tractors....that is, there is not an emergency brake warning light. I can't tell you how many times in a day I drive around with my parking brake on. Very frustrating...and it is not my fault - the tractor manufactures are to blame. :p

However, my L48 has a parking brake light on the dash and I drive around with it on anyway. :eek: :mad:

Very nice. I'm envious.
I'm toying with the idea of adding a turbo to it and bumping it up to about 26 HP.:D
I'm not sure though I might end up breaking something if I do.:eek:

In regards to your parking brake, how many notches on the catch does it take for you to get a good stiff pedal?
Are you locking the two pedals together too?
If it's too many you might need new shoes, or it's way out of adjustment.

Brakes lock solid at 3 notches, and the pedals are locking together.

I was looking for the brake drums this afternoon, and I didn't see anything that looked liked brake drums, at least not the automotive kind.

The brake push rod went into a small housing, and if there's a brake drum in there, it must be very small.

As a side note, it's estimated that my B7100 was manufactured in 1997, if this makes any difference.

Parking brakes - what are they?

After driving around too many times with them set, I have prevented that problem by no longer using them. Yes I occasionally need the brakes for stopping or holding on a hill, but for parking I just drop the loader and 3-point. Should do that anyways as they will go down on their own, but I have never moved very far with the loader down.

Do you have a shop manual yet?
PM me an email and I'll send you a copy.

Here is what it looks like.

YEP there is a bunch of stuff in the way before you'll see the drums. I put new shoes on my B6100 a while back and took some diggin to unveil the drums. Seems to me they are more like an internal break drum inside the axle.

I was under the impression that most Kubotas have "wet brakes" that operate in hydraulic fluid.

My L3650 and all current tractors have a "drum"-type enclosure just inboard of the rear wheels. A hydraulic fluid drain plug is in the lowest area to drain the oil.

Maybe that is an erroneous thought. Eric McCarthy can probably clarify this since he put on new shoes.
